Some cable companies set the Mac address in the cable modem itself preventing more then one computer from using the cable modem thru a hub.

Now by powering off the cable modem, waiting a few minutes and powering it back on may allow the cable modem to reset the MAC address. That has only worked for me one time with one of the cable internet companies around here.

Most of the time I have to call the cable company for tech support and tell them the network board was changed and give them the new MAC address so they can set it in the cable modem.

John,

Your MAC address is different from your adapter address, believe it or not. I discovered this after installing my 3com Office Connect. You also need to contact your provider to 1) ensure it is on their "list of approved" or compatible devices. 2) So they can ID and provision your device. If they tell you it isn't compatible, ask to have the call escallated. Usually they have Phone Monkeys that know less than most people. I usually deal with the HSD supervisor when I have issues.

Good Luck!

One last thought, although when you call your provider, they will likely have you do this: Make sure your LAN settings are set to autodetect. Also, the IP is dynamically assigned by the DHCP server.

If you're reading the modem and you're getting data transfer, try pinging a website. Go to a command prompt and type "ping www.yahoo.com" (no quotes) and see if you get a reply. If you don't, type "ping 64.58.76.230" (yahoo's ip address).

If youcan't get a reply either way then call your isp. If you only get a reply with the ip address then you need to set your dns server information. If you're getting a reply with both options, then start Internet Explorer, click the File menu and make sure that Work Offline is not checked.
